This invention relates to manure spreaders, and has for an object theprovision of a practical and successful machine of that type having suchnovel construction and arrange- 5 ment of parts that a distinctlysuperior machine is obtained without having its driving axle above thebottom of its moving load mass. y

Users of machines of this class demand that such a machine shall berugged and yet be as light in weight as possible; they demand that itshall be compact, yet have maximum capacity; they demand that it shallhave the vminimum of parts, yet be ableto perform its varyingconditions; they demand that it shall be light of draft, and that itshall be such that it may be loaded with a minimum of labor. Theillustrative machine meets those demands.

In the accompanying drawings,-y Figure 1 is a side elevation;

Figure 2 is a vertical section* particularly illustrating the relativearrangement of the axle,`body sills, apron, and load supporting bottomof the machine; A

Figure 3 is a view mainly in plan, showing the rear part of the machinewith the arrangement of the axle, bottom extension, bearing boxes, andapron particularly FigureV 4 is a detail view, showing the relation ofthe axle, the bearing-box, and the side wall of themachine at one sideof the' machine; e

structure of the bearing box and its relation to a Vretainer securedtothe side wall; and

Figure 6 is a detail view ofthe retainer. Referring tov the drawings,-there is disclosed a manure spreader body having supporting sills 10embracing the laxle 11, as indicated in Figure 2. vCompactness of bodyconstruction 'and facility of loading of the illustrative machine ispromoted by the particular sill structure shown.Y This includes thedownwardly and rearwardly bent portion 12 and the adjoining upwardly andrearwardly bent portion 13. Between these bent portions of the sills andthemain bottom por- '0 tion 14 of the illustrative machine the axle isvarious functions successfullyunder many` Figure 5 1sy a( detail viewillustrating thel located. rlhe main bottom portion preferablyterminates forwardly of the axle, as clearly shown in Figure 2, therebeing secured to this portion an extension 15 preferably in the form` ofa steel plate which just clears the top of the axle, as shown. Thisplate is vsecured to the mainlbottom portion 14 so that the top surfacesof these two members are in the same plane.

lThe load supporting body of the machine is completed by side walls 16and 17 located above the opposite sills 12'. Theseside walls are rigidlysecured to the bent vportions 12 and 13 of the sills by supports shownas parallel uprights 18 and 19. As indicated in Figure 4 of thedrawings, these uprights are offset outwardly of the side wall 16, sothat the weight of the machine will be uniformly distributed over thebearing boxes 20, which preferably contain roller bearings for the axle11. The uprights are connected by a retainer 21 which yengages a bearingbox to support thei'weight of the machine. v This retainer snugly fitsbetween two upwardly extending lugs 22 and' 23 preferably integral withthe bearing box, as indicated in Figure '5 of the drawings.l .Thisarrangement pre- 'vents side slipping of the axle or the wheels relativeVto the body of the machine.

The retainer 21 also engages the bearing box 20. in such a manner as to.prevent rotation of that box with the. axle. To this; i end" theretainer is formed with a notch, as ,indicatedat 24 in Figure '6 of thedrawings. 85

This notch receives a projection 24 which forms an obstruction to thegroovevformed by the lugs22 .and 23. The bearing box 2O is alsoV formedat its'lower end 'with aflat faced lug. 25 whichengages therhorizontall,fiat portion of the sill 10 to prevent turning of the bearingbox andadequately maintain the parts in their proper positions. Y.

: As indicated in' Figure the extension or plate 15 is yinterposedbetween the bearing boxes 20 on opposite sides ofthe machine. Due to thefact that the plate 15 just. clears the axle, the bearing boxes extendinto positions above the-plate'. 'This arrangement of elements promotes`lovvn'ess of body construction and, therefore, facility 3 of thedrawings,

of loading. In Figure 3, the apron or conveyer 26 is partly cut away soas to show the above described structure. Cut out portions of the plateI5 are also shown, as indicated at 27. rIhis formation is for thepurpose of receiving the apron sprockets 28, whichv so guide the apronthat its upper run moves along the top surface of the load supportingbottom of the machine.

The manure spreader, as shown in Figure l of the drawings, includes aconventional wide spreading device 29 and a front trucl construction 30,the latter being associated with a tongue 3l and a steering device 32.These devices form no part of the present invention and they are,therefore, not described in detail in this application.

Althoug i the invention has been described with reference to oneparticular construction, itis to be understood that the invention is notlimited to the details thereof, but that it is of ascope commensuratewith the subjoined claims.

lflvlhat is claimed as new is:

l. In a manure spreader, a rearaxle, a pair of longitudinal sills havingportions bent down so as to pass beneath said r ar axle and disposedthroughout the major portions of their lengths with their top surfacesabove the lower side of said axle, bearing boxes located between thebent portions of each sill, and a tight lixed bottom supported by saidsills with its under surface just clearing the top of said axle.

A manure spreader comprising, in combination, a load carrying body, afixed load supporting bottom for said body having its top surface lyingin a single plane, a rearward extension of said bottom of less thicknessthan the bottom and having its top surface in the same plane, and athrough driving axle rotatable through the lower horizontal coni'ine ofsaid bottom and ust clearing the under side of said extension.

, 3. A manure spreader comprising, in combination, body side walls, athrough axle extending across the side walls, a main bottom ypartterminating forwardly of the axle with its top surface lying in a planejust above the axle and having the greater part of its body lying withinthe horizontal confines of the axle, anrextension secured to the mainvbottomopart with its top surface in the saine plane and extending overthe axle, and axle bearing boxes on the axle at either end of theextension and substantially contiguous thereto, said bearing boxesextending above the plane of the top surface of said main bottom portionand said extension and being secured beneath the body side walls.

t. A manure spreader comprising, in combination, body side Walls, athrough axle extending across the side walls, a main bottom partterminating forwardly of the axle with its top surface lying in a planejust above the axle and having the greater part of its body lying withinthe horizontal confines of the axle, an extension secured to the mainbottom part with its top surface in the same plane and extending overthe axle, axle bearing boxes located on the axle at the ends of theextension and substantially contiguous thereto, and means secured to theside walls for holding the bearing boxes from rotation and formaintaining them in position under the side walls.

5. A manure spreader comprising, in combination, body side walls, athrough axle extending across the side walls, a main bottom partterminating forwardly of the axle with its top surface lying in a planejust above the axle and having the greater part of its body lying withinthe horizontal confines of the axle, an extension secured to the mainbottom part with its top surface in the same plane and Vextending overthe axle, fixed bearing members surrounding the axle and so arrangedthat the extension is located between them and lies below their tops,and means lixed to the side walls for engaging the bearing boxes toprevent them from rotating.

6. i tight bottom manure spreader comprising, in combination, a rearaxle, a pair of sills supported by said axle and being bent downwardlyand upwardly so as to embrace said axle, a fixed bottom bridging thebent portions of the sills and just clearing the top of said axle, sidewalls above the sills, and uprights, connecting the bent portions of thesills with the side walls above them, said uprights being located onboth sides of the axle at each side of the machine.

7. A tight bottom manure spreader comprising, in combination, a rearaxle, a pair of sills supported by said axle and being bent downwardlyand upwardly so as to embrace said axle, a fixed bottom bridging thebent portions of the sills and just clearing the top of said axle, andbearing boxes located be- `ween the bent portions of each sill.

In testimony whereof I afx my signature.
